November 16, 2015 Crash when iterating over files with foreach and std.file.dirEntries on Windows? | ||||
---|---|---|---|---|
| ||||
I'm wondering if anyone has experienced a crash when using dirEntries to iterate over files. This is for the Windows 32 bits build of gdc from the gdc downloads page and it happens for both the 5.2.0 and 4.9.3 gcc versions (I haven't tried any others). It works correctly for the 64 bit builds though. I'm wondering if this is a known issue (I couldn't find anything) or if I should get a minimal example going. Crash seems to happen when exiting a foreach loop. |

I think somebody already reported this. The windows builds are unsupported right now and there are likely many similar issues. I hope we'll have stable MinGW builds at the end of this year.

Should I file an issue in the bugzilla just in case? And if it makes you feel better, this is the first issue I've encountered with the MinGW builds.

yes you should and please post the code you have used because I would be curious to reproduce it myself.
Thanks

Absolutely. I'm going to spend some time narrowing this down and making sure I know what exactly is causing it before I post any code though.

After minimizing my code, I am now wondering if it has something to do with ranges in general or if it is related to just dirEntries. This will cause a crash:
module test;
import std.stdio;
import std.file;
void main(string[] args)
{
writeln("Testing");
auto directoryEntries = dirEntries("C:\\", SpanMode.shallow);
writeln("fails?");
}//crash on exiting the scope
And if we try to do something with the range we get a crash earlier.
module test;
import std.stdio;
import std.file;
import std.array;
void main(string[] args)
{
writeln("Testing");
auto directoryEntries = array(dirEntries("C:\\", SpanMode.shallow)); //crash here
writeln("fails?");//never printed
}

Posted in reply to Jeremy DeHaan | Just to reiterate, this happens with 32 bit gdc only. The 64 bit gdc works correctly for this. |
